AECOM vs Bilfinger: Which Stock Looks Stronger in 2026?

Bilfinger SE holds the cleaner structural position, with growth as the main driver and stability adding further support. Both sides have seen trend damage — neither carries a clear market edge right now. With both trends damaged, the structural comparison carries most of the weight here.

The comparison is based on similar long-term financial trajectories, not sector labels. Peer scores are normalised within each company's primary universe (ACM: Russell 1000, GBF.DE: HDAX).

Gap+43in favour of GBF.DE

One company is still expanding while the other is contracting, which creates a very wide growth split.

What keeps the gap from being one-sided

AECOM still carries lower volatility exposure — that difference is real enough to prevent the comparison from becoming one-sided.

What this means for the comparison

Growth is the clearest driver, and stability also supports Bilfinger SE's broader structural position.

How AssetNext Peer Scores Work

AssetNext scores reflect each company's structural position within its functional peer group — not a ranking against all stocks simultaneously. Peers are identified by similarity across eight financial dimensions, including revenue growth trajectory, margin structure, capital intensity, and earnings stability. A score of 75 means the company ranks in the top quartile within its own peer group, not the entire market.

Four dimension scores drive the overall peer score: Growth (revenue trajectory and expansion dynamics), Quality (margin structure and capital efficiency), Valuation (peer-relative pricing on standard multiples), and Stability (earnings consistency and financial predictability). Each dimension is scored 0–100 relative to the peer group, then combined into an overall peer score using equal weighting.

Because scores are peer-relative, the same company can have slightly different scores in different index universes. On comparison pages, both companies are shown within their shared peer universe wherever possible — so the scores are directly comparable. The peer basis is stated on each score card.

Scores are recalculated periodically as underlying financial data is updated. All analysis is descriptive and rule-based — AssetNext describes structural realities and never issues buy, sell or hold recommendations.
